Organize, motivate, direct. That's how STEEM wins.
It's been a while, but in the past I've yammered on about the five step model to get people to do what you need. And I'm reminded that the guarantee of a reward's delivery plays an important role in that system -- the system that made recruiting on STEEM successful.
But push for STEEM's promotion never ends and so campaigns that reward Steemians for promoting their favourite platform continue:
Good luck!
P.S. There's a new initiative designed to further reward developers and enterprisers on STEEM -- even if you aren't one it may be worth following just to track the folks it promotes.
